Case report of a COVID-19-associated myocardial infarction with no obstructive coronary arteries: the mystery of the phantom embolus or local endothelitis
Abstract
Abstract Background Since the first documented outbreak of a novel severe acute respiratory syndrome inducing Coronavirus in China at the end of 2019 the virus has spread to all continents, leading the WHO to declare a pandemic in March 2020. While this virus primarily targets the alveoli in the lungs, multiple authors have described an increased rate of thrombo-embolic events in affected patients. We present this case of a myocardial infarction with no obstructive coronary atherosclerosis in an otherwise healthy 48-year-old patient. Case summary A 48-year-old female, presenting with chest pain radiating to her left shoulder with no cardiovascular risk factors other than genetic predisposition, was screened for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and tested positive. Although computed tomography angiography excluded obstructive coronary heart disease, cardiac magnetic resonance imaging showed an acute myocardial infarction with no obstructive coronary arteries of the inferior wall. The patient was treated with dual anti-platelet therapy, an angiotensin-converting-enzyme inhibitor and a statin, and assigned to a cardiac rehabilitation program. Conclusion We report a serious thrombo-embolic event during an oligosymptomatic SARS-CoV-2 infection in a healthy, young patient. While these two diseases may have occurred simultaneously, by chance, it is possible that the pro-thrombotic effects of the SARS-CoV-2 infection facilitated the infarction. This case…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
